Right, here's what happens now. There is no ZLP in this instance. I've added some debugging printks to make things clear. <7>udc: USB suspend <6>lab: Please plug in the cable. <7>udc: USB resume <7>udc: USB reset start <7>udc: USB reset done, gadget driver 'char' <7>udc: SETUP 00.05 v0019 i0000 l0000 Broken hardware!

Still no set config. I'd WBM about people not testing code before committing it (or at least not testing it on all possible hardware configurations, even the most obscure :P) but I couldn't do it any better :P > - Dave /j - -- Joshua Wise | www.joshuawise.com GPG Key | 0xEA80E0B3 Quote | <lilo> I akilled [EMAIL PROTECTED] by mistake -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQE/kLgpPn9tWOqA4LMRAi9nAKCqnQCP0Vp4PpBA7t8yMyLOUIxqrwCgj5zE +yZzHXZXJqIImfVy9KhIXxI= =6Na4 -----END PGP SIGNATURE----- ------------------------------------------------------- This SF.net email sponsored by: Enterprise Linux Forum Conference & Expo The Event For Linux Datacenter Solutions & Strategies in The Enterprise Linux in the Boardroom; in the Front Office; & in the Server Room http://www.enterpriselinuxforum.com _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
